 #### 3. Module development
 This section contains all the information about the development of the module. Read it if you intend to gain insight about the implementation or you plan to improve or debug it.
 ##### 3.1 Implementation
-The module uses the CWirelessPower object built inside MRPT. It is included in mrpt/hwdrivers/CWirelessPower.h. \[NOTE: at the moment of writing this document, it is still in mrpt/utils/CWirelessPower.h. This note will be removed when the file is moved to its final location\]. CWirelessPower offers an interface to the Wifi subsystem in an OS independent manner. WifiWatch periodically requests the CWirelessPower object for a measurement, and publishes the results.

 ##### 3.2 Limitations of the implementation
 In Linux, CWirelessPower uses [Wireless Tools](http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html). To obtain an updated value of the power, a scan must be performed. This operation requires superuser rights. Thus, WifiWatch will ask for the root (or user, depending on the sudo settings of the system) password before starting to monitor the network.

###WifiWatch

#### 1. Overview The WifiWatch module periodically measures the signal strength (%) of a specific wireless network, given by its SSID and the name of the interface. It provides other modules with this information through the OpenMORA board. #### 2. Usage ##### 2.1 Configuration file The WifiWatch module reads its main configuration from the pWifiWatch section of a mission file. The parameters read from this section are: 1. AppTick: The value of AppTick must be kept low, otherwise the module might fail. A value of 1 is good. 2. CommsTick 3. GUID: Interface used to monitor the network. Usually there will be only one. In Windows, the GUID can be obtained in the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards\X). Remember that the braces ({}) must be included. 3. SSID: Name of the network to be monitored. ##### 2.2 OpenMORA variables The signal strength will be published in the WIFI_POWER variable. #### 4. Module development This section contains all the information about the development of the module. Read it if you intend to gain insight about the implementation or you plan to improve or debug it. ##### 4.1 Implementation The module uses the CWirelessPower ##### 4.2 Limitations of the implementation ##### 4.3 Tests ##### 4.4 Bugs ##### 4.5 TODO ##### 4.6 Interesting links
